Inspired by the wonder of the night sky, our Glass Glowing Ball Garden Ornament will add a magical feeling to any yard or garden. Easily hang our glass solar ball garden accent from a tree, umbrella, soffit or place in a picture window indoors and prepared to be mesmerized by its celestial, stardust glow. Our beautiful hand-blown, bubbled glass solar ball ornament is an attractive by day and glows in the dark at night. Luminescent crystals suspended in the translucent glass absorb the sun’s energy, to release a soft green, speckled glow at dusk. Weather-resistant ball's glow duration may last up to four hours, gradually fading over that time. Family and friends will be impressed with this solar garden décor's unusual, whimsical appearance! For brightest glow, place glass garden ornament in full sun.
